Recovery at Morvin: SERPENT final report [PDF]

open access: yes, 2010
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

From Copper Nanoparticles to Alumina Encapsulated Porous Layers With Enhanced Mechanical Stability

open access: yesAdvanced Materials Interfaces, EarlyView.
This study analyzes the synthesis‐structure relation of individual Cu nanoparticles and highly porous nanoparticle‐based Cu films using different sputtering‐based nanoparticle sources. The inherent mechanical instability of the films is tackled with Al2O3 encapsulation through atomic layer deposition, enabling 4‐fold increase in critical force in ...

Experimental evaluation of an environmentally friendly drilling fluid for clay stabilization in shale formations

open access: yesScientific Reports
To face the problems of shale drilling, oil-based fluids, mineral salts, and polymers are used, but they have limitations such as high preparation cost, hazardous environmental impact, and limited applicability in high-pressure, high-temperature ...

Drilling fluid for deep water drilling.

open access: yesJournal of the Japanese Association for Petroleum Technology, 2003
In recent year, deep water drilling has become to go deeper area. It is not only oil and gas exploration, but also Methane Hydrate exploration and scientific drilling. In general, deep water drilling has a greater degree of difficulty than conventional drilling.
